Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing transformer cores are inefficient and costly due to the need for multiple laying tables and manual handling, leading to downtime and high costs when producing various types of cores.
Innovation Solution
A robot system with a multi-axis robot, conveyor device, and control device that allows for flexible positioning and storage of sheets on laying tables with threading bolts or sheet metal stops, enabling cost-effective production by minimizing downtime and reducing the number of laying tables required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple laying tables are used to produce different transformer core types, then production versatility is improved, but device complexity and costs increase
Solution Approach 1:
The patent implements a single laying table that can produce multiple transformer core types by making the positioning aids (threading bolts and sheet stops) movable and repositionable. The control device manages the repositioning of these aids to accommodate different core geometries, allowing one table to perform the functions previously requiring multiple dedicated tables.
Solution Approach 2:
The positioning aids are designed to be dynamically repositionable during operation. The threading bolts and sheet stops can be moved along the laying table to different locations based on the specific transformer core type being produced, transforming a static setup into a dynamic, adaptable system.
2Adaptability or versatility
If manual handling and multiple laying tables are used, then flexibility in producing various core types is improved, but productivity decreases due to downtime
Solution Approach 1:
The control device automatically manages the repositioning of positioning aids and the feeding of sheets, ensuring continuous operation without downtime. When one laying table is in use, another can be prepared with the required positioning aids, or aids can be repositioned during idle periods, maintaining continuous productive action.
Solution Approach 2:
The system uses automated control devices and robotic handling to reposition positioning aids and manage sheet feeding without manual intervention. The system serves itself by automatically adjusting to different core types and maintaining continuous operation.
3Manufacturing precision
If threading bolts and sheet stops are permanently mounted, then positioning precision is improved, but adaptability to different core types deteriorates
Solution Approach 1:
The positioning aids are made dynamically repositionable while maintaining precise positioning capability. The threading bolts and sheet stops can be moved to exact required locations along the laying table and securely fixed, combining the precision of permanent mounting with the flexibility of temporary positioning.
Solution Approach 2:
The control device pre-calculates and pre-positions the threading bolts and sheet stops to the required locations before sheet feeding begins. This preliminary positioning ensures precision is maintained while allowing rapid changeover between different core types.
